Syringe Filter Selection for HPLC or LC/MS samples
Nov 15, 2014 · The choice of syringe filter depends on the: filter size (volume) of your sample, the chemical compatibility of the housing and membrane and desired pore size.Selection of the wrong filter size can result in too much sample holdup volume (loss of sample on filter) or overloading of the filter (allowing unfiltered material to pass through).

What can I do when my filter membrane leaves impurities in
Nylon filters tend to be more 'extractable' and leave behind less impurities (e.g. better for hplc sample prep); althought, their chemical resistance is not as good. Finally..if it all fails.
